OK LJ turners, I need your wisdom. I have 2 (had three) pieces of very beautiful spalted maple that leans to the punky side in areas. I tried turning one this morning for a peppermill and areas of it were so soft/punky that it chipped out and was not acceptable (my standards) to finish and try to sell (I can salvage it as bottle stoppers). I have used super glue in the past to secure cracks and small areas of softness but that stuff gets expensive. I know I have heard/read here on LJ of a product but the name of it escapes me at the moment. So help me out and tell me what you do in this situation. I don’t want to throw these pieces in to the burn pile as the spalting is just gorgeous and will make very beautiful peppermills.

Polycryl is the product I was thinking of. Has anyone used it for the purpose of stabilizing soft/punky wood? Another product that I just found on another blog, Rotten Wood Hardener made by Bondo, and said to be found at Lowes. Anyone use this one as well? Or even heard of it. Any ideas/suggestions are very welcome.

I have used a very thin epoxy sealer, Industrial Formulators S1 Sealer for years to “save” punky spots where rot had started in boats. It is basically a two part epoxy mixed in lacquer thinner that will go about anywhere diesel will go. It is even foodsafe.
The problems are:
1) You may not be able to stain / dye after using it
2) You may have trouble finding it as it’s a Canadian company. The company was bought by System Three several years ago but still sells (in Canada anyway) under the Industrial Formulators of Canada name. You’re not far from Canada anyway so If you like I can get you store info on it.

Anyway it hardens up soft wood amazingly and kills (encapsulates I guess) rot.

Polycryl is very good at stablizing soft or punky wood without turning it into plastic. I’ve used it before but it is expensive as heck. As well as Pentycryl another wood stabilizer that’s supposed to keep your wood from cracking. I never had much luck with it. Anchorseal always worked better for me as for cracking went. Polycryl is a polimer based product that gets into the fibers and hardens them like any plastic would but doesn’t seem to make the wood look plastic or get real hard.

Thank you Paul & Mike. Mike, did your get together go well? I am going to Rockler next week (with coupon in hand) and will get some Polycryl and give it a try. I have high hopes. I think I may be able to save the original peppermill. At least I’m going to try.
Paul – a belated welcome to LJ. Thought many times of spending my winters in AZ but the wife doesn’t like the heat. So, I guess we’re here to stay in the rainy NW during the winter (west side of the hill only, local joke). By the way, NICE shop. There’s one major difference between your shop and mine. Yours is CLEAN…...

Trust me Jim, your shop is a lot more like mine than you think. I did a major cleanup for the photos.
